How to a create a random phyton program generator? [closed]

Don't ask why, but I want to create a Python program that generates random Python program that is valid for execution. I found a similar thread Searching for a random python program generator , but it's old and all the links except the demonstration http://www.4geeks.de/cgi-bin/webgen.py are dead. And maybe something has changed in these years and it's easier to do such thing?

One of idea is to use quantum collapse algorithm/technique. This would require to make a kind of database, where I describe what symbols can came after previous one. For example after a can come (,, any letter, etc, but never, for example, ). Still I think this will create very gibberish source and I could easily set wrong conditions.
